It is not likely that a bee knows she will die after stinging anyway. Their behavior is instinctive.
It is true that a bee will sting only if hurt, frightened, or in defense.
I suppose they are trying to "teach" potential predators to avoid bees. By giving her life and stinging a predator, she teaches them that bees are painful and thus save other bees in the future by teaching the predator to avoid them. Bees will also sting when the hive and queen are at risk.
Because workers are all sterile females and therefore don't leave their genes to a next generation whether they sting or not. If they sting, they die without leaving behind another generation. If they don't sting, they die without leaving behind another generation.
This is because of the antibodies produced in our bodies..,These antibodies help us and guard us against such antigens produced by bees..Thus the antibodies which are produced by our body protect us from more destruction..!
My cousin was stung by a bee yesterday and people always say how a bee only stings when they're afraid or in defense mood but it costs them their life. But Is that to main main reason why ?
